[原文]MyProxy 6.58 allows remote authenticated users in the Users Tab to connect to arbitrary hosts from the MyProxy server, possibly bypassing access restrictions, by connecting to the proxy and issuing a CONNECT command.
MyProxy contains a flaw that may allow an authenticated malicious user to use the proxy as a relay. The issue is triggered when a malicious user invokes the CONNECT command to connect to arbitrary ports on arbitrary servers. It is possible that the flaw may allow arbitrary host relay resulting in a loss of integrity.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
